ROTARY-ROD WEEDER.

The present invention relates to weeders of the rotary rod type and .it especially has for its object to provide a wee-der of the wheeled species of a compact design so that the distance between the supporting and driving wheels need A not exceed the length o f the rotary rod, thus reducing the side spread of the weederrover former weeders where the driving connection between the driving wheel and the rotary rod had to be located on the inner side of the driving wheel. In the present invention, the driving mechanism'is located on the outer side of the driving wheel and the driving wheel and supporting wheel are located directly in front oi' the rotary rod and not spaced a art greater than the length of the rotary ro ln its more detailed'nature, the invention resides in those novel details of construction, combination and arrangement of parts, all of which will-be rst fully described, then be specifically pointed out in the appended claims, and illustrated in kthe accompanying drawing, in which:

lFigure 1 is a plan view of a weeder embodying the invention.

Figure 2 is a side elevationl of the same.

Figure' 3 is a detail perspective view of the lremovable bearing member.

Figure i is a side view of the removable bearing member.

.Figure 5 is a detail elevation of the gooseneck standard and removable bearing member adjusted for use in soft ground or sandy soil.

Figure (i is a diagrammatic rear elevation of the invention.

ln the drawing, in which like numerals of reference indicate like parts in all of the figures, the frame of the Weeder is composed.

mtting connection between the shaft 8 and the rotary rod 12. rllhis may be the usual tumbler rod 10 having the universal @cinte 11 or any other suitable power transmitting connection may becmployed.

The chain 15 takesA over an idler roller 16 4on the shaft 7 and over lan idler sprocket or standards which in the preferred embodiment of the invention are of the goose-neck type and they carry removable bearing mem-A bers 21,- the construction of which is .best indlcated in Figures 3 and 4 of the drawing. Each bearing member 21 comprises a shank 22 having ianges 23 adapted to fit on the ends of the goose-necks and be secured thereto by sultable bolts and nuts 35. Each bearing includes a removable half 'bearing member 24 having a shank 25 to liein the aperture 27 of the shank 22 flush with the same and through which one ofthe bolts passes. The removable half bearing member 24 sets in the recess 26 of the main bearing' member 22 and cooperates with the half bearing member 29 ot the main bearing member. The half bearing face 28 of the member 24; matches the bearing face 29. The usual rod carrying bearing member 34v is employed to ride in a bearing surface 28-29.

The reference numeral 30 is the point of the shoe which in the resentv embodiment of the same is of the plow type7 it having the plow point 33 formed at the junctureof the edges 32 and 31. lt will be noticed that both edges 31--32 are directed in the same direction from the axis of the bearing, that is-they both extend forwardly and downwardly` Ltrom'the axis, the edge 31 being more nearly horizontal than the edge 32 so that when the arts are positioned as shown in Figure 2 t e bearing member will be adapted for hard soil and by reason of its shape will tend to penetrate the ground as the weeder is pulled forward. Then used in sandy or soit soil where the penetration of the rod in the ground is easy, the bearing is reversed, as shown in Figure 5 and then it has a tendency to ride up out of the ground, thus preventing the too deep penetration of the rotary rod into the grou-nd.

The draft head clevises 36 are attached to the :trent er the Weeder frame in any desired manner. c

te shown in E'iggure l, the supporting wheel 3'( is mounted on the axle 39 that is journalled in bearings 4:0 on certain of the bars 2, the axle 39 aligning with the axle 4 of the wheel 5 in the preferred arrangement. lt will also be noticed that the supporting wheel is located between a pair of goose-neck bearings instead 'of to one side ot the frame and the driving wheel 5 is located close up to the longitudinal beam 2 which carries the goose-neck 20 at one side oi" the machine while the power transmitting connections 13-14-15 lie outside `of the wheel 5 or between it and the extreme end of the frame, ln this way, the over-all width of the frame is greatly reduced from the present practice.

While l have shown and described a novel reversible rod bearing member in this application l desire it understood that the same, per se, forms no part of the present application.

From the foregoing description, taken in connection with the accompanying drawing, it is thought the complete construction, operation and advantages of my invention will be readily understood by those skilled in the art to which it appertains.

What l claim is:

1. In rotary rod weeders, a frame, rod Acarrying standards depending from the iframe at intervals, a rotary rod journalled in bearings on said standards, a supportin wheeland a driving wheel mounted in sai iframe, the distance between said wheels being less than the length of said rotary rod, a power transmitting mechanism mounted on said frame on the outer side of said driving wheel and connected therewith and including a driving connection with said rotary rod.

2. ln rotary. rod weeders, a rectangular trame having end longitudinal beams, intermediate longitudinal beams and iront and back cross beams, a supporting wheelv and a driving wheel journalled in bearings in said frame, standards carried by said frame at intervals across it, rod bearings on said standards, a rotary rod journalled in said bearings and of greater length than the distance between said wheelsa countershaft journalled in bearings in said trame and located at the outer side of said driving wheel, power transmitting connections between said driving wheel and said countershatt, and ower transmitting connections beween sairlcountershaft and said rotating ro 3. ln `rotary rod Weeders, a rectangular frame having end longitudinal beams, intermediate longitudinal beams and front and back cross beams, a sup orting wheel and a driving wheel journalled) in bearings in said frame, standards carried byl said frame at intervals across it, rod bearings on said standards, a rotary rod journalled in said bearings and of greater length than the distance between said wheels, a countershaft journalled in bearings in said frame and located at the outer side of said driving wheel, power transmitting connections between said driving wheel and said countershaft, power transmitting connections between said countershaft. and said rotating rod, said standards comprising goose-necks mounted on the frame to the rear of said wheels, and a plank mounted on said frame and projecting to the rear thereof for the operator to stand on and shift the center of gravity of the weeder.

4. ln rotary rod weeders, a rectangular frame having end longitudinal beams, intermediate longitudinal beams and front and back cross beams, a supporting wheel and a driving wheel journalled in bearings in said frame, standards carried by said frame at intervals across it, rod bearings on said standards, a rotary rod journalled in said bearings and of greater length than the distance between said Walls, a countershaft journalled in bearings in said frame and located at .the outer side of Said driving wheel, power transmitting connections between said drivingwheel and said countershaft, powertransmitting connections between said, countershaft and said rotating rod, said supporting wheel being located in :front of and between one pair of standards at one side of the machine and said driving wheel being mounted infront of the standard at the other side of the machine and to one side thereof.

5. In rotary rod weeders, a frame, rod carrying standards depending from the frame, a rotary rod journalled in bearings on said standards, a supporting wheel andv a bearing wheel, mounted in said frame in advance of said rod, said rotary rod being of greater length than the distance between said driving wheels, reduction earings mounted on said frame to the outsi e of the drivin@ Wheel and. operatively lConnected with the same and with the adjacent end of the rotary rod for the purposes described.
